SPECIFICATION forming part of Letters Patent No. 530,714, dated December 11, 1894. Application filed April 28, 189] Serial No. 390,812. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES F. OLQESE, a

citizen of the United States, residingin the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Window-Sashes, of which the following is a specification.

This invention relates to improvements in window sash, and more particularly to sliding window sash not removable from the window frame for cleaning or other purposes, without removing the sash and parting strips, and detaching the sash from its pulley cords.

In sash of the character referred to, the necessary cleaning of the windows frequently involves not only exposure to inclement weather, but danger of life and limb to the person attempting to clean it, and this is particularly true in the cleaning of windows at dizzy heights such as of late years occur by reason of high buildings, and the correspond, ingly increased exposure to high winds. Very large elevated windows increase the danger, as opposed to smaller windows, because of the distance required to be reached by'the attendant in cleaning them, tending to destroy his equilibrium when he is in such a position as to have little or no hold for sustain-. ing himself, even when in a perfect state of equilibrium.

The prime object of my invention is toprovide improved fastening devices for use in connection with inwardly opening supplementary sash employed to enable the cleaning and insertion of glass in sliding window sash without removingthat sash, or disturbing its position at all, and without exposing the attendant to any danger whatever, and to do this without changing the present outline of said sash, or its manner of attachment with its suspending weighted cords. These and other objects hereinafter described and claimed are attained by the devices illustrated in the accompanying drawings, in which- I a Figure 1, represents an inside front elevation of a window sash embodying my invention with its parts broken away for illustrating the attachment of the usual cord and window weight; Fig. 2, a centrallongitudinal section through the same with the supplemental sash swung to an open position, and with main and supplemental sash together and locking them; Fig. 5, a detail perspective view showing a modified form of the latch or locking device connecting the main with-the supplemental sash; Fig. 6, a top plan view partly in section,showing a modifiedform of the hinge connection between the main and supplemental sash whereby the concealing of the hinge is provided for; Fig. 7, a detail view of both sash partly broken away, more particularlyshowing a side elevation of the latch device; Fig. 8, a detail view showing the keeper for the latch bolt; Fig. 9, an elevation of the key; Fig. 10, a sectional view through the latch bolt on the line 10, 10, of Fig. 7.

Similar letters of reference indicate the same parts in the several figures of the drawlngs. A, represents a window frame; B, a weight; 0, a suspending cord therefor, and D, a ord pulley, all of which parts are of the ordinary and usual construction.' Sliding in this window frame, and connected with a weight cord in the usual manner, is an upper sash E,

shown in its elevated position in Figs. 1 and 2, and in its lowered position in Fig. 3.

The sash E in outline isa complete and sliding sash and is held in the framein the usual manner, but instead of being glazed in the usual manner, is suitably 'rabbeted on the inner side to receive the supplementary'sash. To this sliding or main sash is hinged by the hinges F, a supplemental sash G, the contour of the outer edges of which are made angular to correspond with and fit into the sliding or main sash as shown at G, so that when the two sash are united they present the appearance of being, and are, so far as their sliding movement is concerned, the ordinary sliding window sash, though at, the same time when the upper and lower sash are in the positions presently to be described, the hinged sash may be swung inwardly away fromthe sliding sash for the purposes of putting in the glass, or cleaningwhen already in.

The sliding main sash and the hinged supplemental sash are locked together by a latch which may consist of an angular thumb-bolt H, shown in detail in Fig. 4:, the said locking bolt being so constructed, that its inner and locking end, by taking hold of the thumbpiece, may be swung into the recess in the supplemental sash, and thereby removed from the sliding sash, or swung into the sliding sash to make the lock, and in order that said locking device may not only look the two sasl1,but tighten the supplemental sash into the sliding sash, the groove or depression in the sliding sash may be inclined or elliptical so that as the locking bolt is turned, the two sash will be drawn tightly together to prevent rattling in high winds, and to exclude air and dust.

In order to provide for inwardly opening the swinging supplemental sash, the upper sash, or better the upper sash frame is made shorter than the lower sash frame I, so that when the lower sash proper is moved to its highest position, and the upper sash to its lowest, the hinged sash G, may swing clear of the elevated lower sash as shown in Fig. 3, and it will be understood that the swinging supplemental sash being at all times upon the inside may be opened in whatever position said lower sash maybe. With this difference in length both sash are precisely alike, and provided with the same convenient devices for locking the hinged sash to the sliding sash, and in this connection it is proper to observe that while the fastening shown is well adapted for the purpose described, it is no departure from the essential feature of my invention to use any other form of fastening, either old or novel in its construction. While it would be no departure from my invention in this particular sense to have the supplemental sash hinged to swing outwardly, it may be remarked that as the advantages of my invention in putting in of glass and cleaning the same is due to the inward swinging of the supplemental sash, such outer hinging could serve no good purpose.

Owing to the manner in which the main or sliding sash is connected with the supplemental or hinged sash, the operation of one does not at all interfere with the other, nor does this combining of the two sashes cause the sash as a whole to present any unusual appearance. Furthermore, my invention is of such a nature-that is to say the hinged sash is united with the sliding sash in such a manner that any ordinary sliding sash may, without taking it to pieces, or decreasing its value be altered by any skilled sashmaker, to contain my invention, and my invention is therefore adapted to be applied to the ordinary sliding sash of the day at a very small expense, and certainly so small that in view of the advantages, safety and convenience in cleaning windows warrants that change.

In order that the supplemental sash may not be opened by children when not desirable, and that said supplemental sash may be perfectly tightened in themain sash, to prevent rattling in wind storms and exclude dust and and air, it is preferred to employ a latch,the bolt of which requires the use of a removable key, without which said latch bolt cannot be actuated, and to have the latch so constructed that it is fixed in whatever tightening position it may have, on the withdrawal of the key from the latch spindle. To these ends, asuitable latch case is sunk or mortised in the supplemental swinging sash,as shown in Figs. 5, 7, and 10, and has pivoted therein, a hollow spindle a, adapted to receive and to be actuated by a key b, (see Fig. 9) fixed on which hollow spindle, is a segmental pinion 0, having cast therewith, or otherwise rigidly secured, a'latch bolt d, which may be thrown in and out of the supplemental sash, so as to disengage and engage with a keeper e, in the main sash. The segmental pinion c, is engaged by a pawl f, actuated by a spring g, to maintain it in engagement with the teeth of the segmental pinion. Pawl f, has projecting therefrom, partly across the bolt of the hollow spindle, which by the key b, may be pushed out of the spin dle so as to cause a disengagement of the pawl with said teeth, to which end, the key b, has a tapering point I), so that as the key is inserted, and before its squared portion b engages a corresponding portion of the hollow spindle, the pawl is engaged. In other words, when it is desirable to actuate the latch bolt, the pawl is disengaged during the insertion of the key, so that by the time it is in position to actuate said latch bolt, the pawl is out of engagement with the mutilated pinion and the bolt free to be actuated by the key. With a latch bolt constructed and operated in this manner, it is not accessible without this key, and after the bolt is adjusted to the desired position, the withdrawal of the key permits the engagement of the bolt with the pinion and maintains the bolt in whatever position it has been turned by the key.

The latch bolt, as before stated, is projected into a keeper e, in the main sash when locking the two sash together, and this keeper is made oblique, with reference to the sash, so that as the bolt descends therein, or ascends, as the case may be, it operates as a cam on the latch bolt and draws the two sash tightly together, in which position they are locked on the withdrawal of the key, as before described, and as a result, the hinged sash is prevented from rattling, and it is so tightened in the supplemental sash that dust and air are excluded from creeping in between the two sash. This latch device is very simple in its construction, and in practice is shown to be effective in operation to accomplish all of the results described, and besides, is very ready of manipulation.

The ordinary hinge illustrated in Figs. 1 to 3 inclusive, while answering the purposes of hinging the sash, is to some extent undesirable because exposed, to provide against which, (see Fig. 4) it is proposed in practice to use a hinge i, consisting of two fiat straps t" and 11 respectively, secured by a pivot i the strap 2', being raised in the upper edge or end of the swinging sash, and the strap 1", being likewise raised in the adjacent wall of the main sash, a similar hinge being provided at the bottom of said two sashes in like manner, whereby said swinging sash, has, as it were, a vertical pivotal movement in the main sash. In order to further conceal these hinges, their straps may be narrower than the recesses in the sash, and a piece of wood corresponding with the sash, fitted in said recesses and conceal the edges of the hinges.

Having described my invention, what I claim, and desire to secure by Letters Pat ent, is-

1. The combination with asliding sash, and asupplemental sash hinged therein, of alatch bolt in one of said sash, provided with a .ratchet and pawl, and a cam-like or inclined dle by a suitable key, substantially as described.
